Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand and understand, the present invention is further explained by combining with the specific drawings.
Referring to fig. 1, the present invention provides a multi-functional center, which includes an upper center mounting plate 100, a reduction motor 200, a synchronizing assembly 300, a lifting assembly 400, a guide assembly 500, and a lower center 600.
The speed reduction motor base 110 and the bearing seat 120 are installed on the upper tip installation plate 100, the speed reduction motor 200 is installed on the speed reduction motor base 110, the guide assembly 500 is installed on the bearing seat 120, the lower tip 600 is connected with the guide assembly 500, and the lifting assembly 400 is installed on the upper tip installation plate 100 and is connected with the speed reduction motor 200 through the synchronization assembly 300.
The synchronizing assembly 300 includes a first synchronizing wheel 310, a synchronizing belt 320, a second synchronizing wheel 320, and a synchronizing wheel mount 340.
The first synchronous wheel 310 is connected to the reduction motor 200, and the reduction motor 200 can drive the first synchronous wheel 310 to rotate.
The synchronizing wheel mount 340 is mounted on the guide assembly 500, and the second synchronizing wheel 320 is mounted on the synchronizing wheel mount 340 and compressed using a round nut and a lock washer.
A flat key 350 may be provided between the second sync wheel 320 and the sync wheel mount 340.
The second synchronous wheel 320 is connected to the first synchronous wheel 310 through a synchronous belt 320, and the second synchronous wheel 320 is driven to rotate synchronously by the synchronous belt 320 when the first synchronous wheel 310 is driven to rotate by the reduction motor 200.
